Landscape conditions and the five year replacement clause

The landscaping condition on your permission almost certainly says that anything which dies, is removed or becomes seriously damaged or diseased within five years must be replaced in the next planting season with a plant of similar size and species, unless the council agrees otherwise in writing. That wording has been in general use for decades, and it binds whoever owns the land at the time, not the person who built the house.

Self-builders tend to treat landscaping as the last item on the programme and the first to be forgotten. The condition is the reason a solicitor's enquiry three years later turns into a problem at the point of sale.

What the standard condition requires

A typical landscaping condition does three things. It requires the approved planting to be carried out in the first planting and seeding season following occupation or completion of the development, whichever comes first. It requires replacement of failures within five years. And it usually makes the approved details themselves subject to prior approval, so the scheme has to be submitted and agreed before anything is planted.

Two traps sit in that first requirement.

The planting season is not the calendar year. Bare root and root balled stock is planted between late autumn and early spring, which means a house completed in May carries the planting obligation into the following winter. Container grown stock can be planted at other times, but it needs watering through its first summer and the condition does not excuse a failure caused by drought.

And "whichever is the sooner" catches self-builders who occupy before the development is complete. Read the wording on your own decision notice rather than assuming.

The five year clause, and what it covers

The replacement period runs from the completion of the development in most versions of the wording, though some authorities date it from the planting. Check yours.

Within that period, four events trigger replacement: death, removal, serious damage and disease. Removal is the one owners overlook, because it catches a deliberate decision to take out a tree that is shading a patio just as much as it catches storm damage. Replacing it with something smaller is not compliance either, since the condition specifies similar size and species.

The obligation is to replace in the next planting season. Not immediately, and not eventually. If a tree dies in June, the replacement goes in the following winter.

Who carries the obligation after a sale

Planning permission runs with the land. A condition binds the land and therefore binds successors in title, so the obligation passes to the buyer on completion of the sale, along with any existing breach.

This matters in both directions. If you are selling, an outstanding landscaping condition shows up in conveyancing enquiries and a buyer's solicitor will ask for evidence that it has been complied with, or will require a retention or an indemnity. If you are buying a recently built house, ask for the decision notice, the approved landscaping details and evidence of planting, and check the site against the approved plan before exchange.

The practical fix before a sale is straightforward: plant what is missing, photograph it, and write to the authority confirming compliance.

Evidence that discharges the condition

Where the condition requires details to be approved, submit a planting plan and schedule: species, stock size, root condition, numbers, spacings, positions on a plan, and the maintenance regime for the establishment period. For anything with trees on it, cross reference the Landscape Strategy or the arboricultural documents so the planting does not conflict with retained trees and their root protection areas.

To evidence compliance after planting:

• dated photographs from fixed positions, ideally repeated each year through the replacement period
• the nursery invoice or delivery note showing species and stock sizes
• an as-planted plan where the layout differs from the approved drawing
• a short statement from the landscape contractor or designer confirming the planting matches the approved scheme

Keep the file. It is the answer to a conveyancing enquiry, an enforcement query and a dispute with a neighbour about a boundary hedge that was supposed to be there.

When planting fails

Failures in the first two summers are common, and the causes are nearly always water, compaction or planting depth rather than the plant.

Watering is the one within your control. New planting needs a substantial soak rather than frequent light watering, through the first two growing seasons on most sites, and a mulch ring holds the moisture and keeps mowers away from the stem. Compacted subsoil under a lawn area is the quiet killer, and it is worth relieving before planting rather than discovering it two years later. The same compaction question arises during construction, which is why ground protection over root zones matters, as set out in our note on retaining a tree through a construction programme.

If a species is failing repeatedly in the same position, replacing it with the same species is throwing money away. That is the point to apply for a variation.

Changing a planting scheme that has not worked

Three routes, in ascending order of formality.

The condition itself usually allows variation with the written consent of the local planning authority, which is the quickest route for a straight species substitution. Write with the reason, the proposed alternative and a plan.

Where the change is more substantial, submit revised details under the same condition for approval, which is a discharge application with a fee.

Where the condition wording itself needs to change, an application under section 73 of the Town and Country Planning Act 1990 to vary the condition is the formal route, and it produces a new permission with the amended condition.

Whichever route you use, do it before the planting season rather than after, and get the agreement in writing. A verbal indication from an officer is not a variation.

Enforcement in practice

Authorities do not patrol landscaping schemes. Enforcement generally follows a complaint, a site visit for another reason, or a conveyancing enquiry that reveals the breach.

The tool is a breach of condition notice under section 187A of the 1990 Act, which requires compliance and carries no right of appeal. The enforcement time limit for breaches in England was changed by the Levelling-up and Regeneration Act 2023 to ten years, so check the current position for your date of breach.

Illustrative example: a self-build house completed in August with an approved scheme of six trees and a native hedge. Planting goes in the following February. Two trees fail in the second summer after a hot spell. The owner photographs them, writes to the authority proposing the same species with an improved planting pit and irrigation, and plants the replacements that winter. The file goes to the buyer's solicitor four years later without a query. Illustrative only.

The habit that avoids all of this is simple. Diarise the planting season, diarise a photograph each year for five years, and keep the invoices.

This is general guidance rather than legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
